You can work with numbers easier with improper fractions. . Raising and Reducing. Pizza. Pizza. 3/4. 6/8. 9/12. Multiply by 1. 5 x 1 =. 235 x 1 =. 2/3 x 1 =. a x 1 =. 5. 235. 2/3. a. What is 1?. . Rasing Fractions. . . . Rasing Fractions. A man walks into the pizza store and orders a medium pizza.. (Part Two). To find 1/8 of something, we divide that thing by 8.. What if we wanted to know what 3/8 of something was? . You’d be doing the same thing 3 times, so you would multiply by 3. . (72 is a whole number – so it’s all in one group. 72 ÷1 is… 72.) . Fractions are used to represent parts of whole numbers . Fractions always have a top and a bottom number. The number at the bottom . (denominator. ) tells you the size of the parts that make the . whole, e.g. . 2/3. 1/4. 1/8. 6/9. 3/8. 7/8. Mrs. Wolfe, grade 5. What is a fraction?. . A fraction is a number that represents .
